Introduction
Cervical adenocarcinoma in situ is usually not cancer. It refers to an epithelial tumor confined to the surface of the cervical canal mucosa and the glands beneath it, with a relatively intact basement membrane. The depth of the abnormal glandular involvement does not exceed that of normal glands, and there is no stromal invasion or necrosis. Therefore, cervical adenocarcinoma in situ generally does not invade other tissues or metastasize, indicating it is not true cancer but rather a precancerous lesion.
Cervical adenocarcinoma in situ is usually not cancer, but rather a precancerous lesion. The specific analysis is as follows:
Cervical adenocarcinoma in situ refers to an epithelial tumor confined to the surface of the cervical canal mucosa and the glands beneath it. Its main pathological features include increased cellular atypia, elevated nuclear-to-cytoplasmic ratio, irregular nuclear size and shape, marked nuclear pleomorphism, and loss of cellular polarity. However, the basement membrane remains largely intact, the depth of the abnormal glandular involvement does not exceed that of normal glands, and there is no stromal invasion or necrosis. Therefore, cervical adenocarcinoma in situ generally does not invade other tissues or metastasize, meaning it is not true cancer, but rather a precancerous condition.
Once adenocarcinoma in situ is diagnosed, patients are advised to actively undergo definitive treatment under the guidance of an obstetrician-gynecologist to prevent progression to invasive carcinoma, which could worsen symptoms and increase treatment difficulty.
